1.7.1 released

Changes for Packagers:
- You will now want to use the --python option to setup.py configure to
make sure the right Python (python2.x) is used. With the Python 3
transition in progress, the lack of uniformity across distros made it
difficult to find a solution that works everywhere. As a result, the
python executable path can be set (for subprocesses launched by Wicd)
with the --python option to setup.py configure, and patching of the
shebang lines may be required if `which python` is not python2.x.
- If you handle translations in your packaging process, setup.py now
needs 'pybabel' and 'xgettext' binaries. Please provide them during
the build process.
- setup.py now accepts three more parameters: --dbus-service=, --systemd=
and --logrotate=. Please set them accordingly to the paths of your
distribution.

Major Changes:
- (New) upstream author: David Paleino :)
- The translations are now handled by Rosetta, in Launchpad.
- Implemented support for wired connections needing authentication with
wpa_supplicant (thanks Joe MacMahon!)
- Support 'Never show networks' (thanks Robin Becker!)
- Mask out sensitive information in the logfile (CVE-2012-0813)
